feat(mcp-cli): add tools command listing stdio tool descriptors

[jsdevninja]

Summary

• Add gittensory-mcp tools [--json] so contributors can list every local stdio MCP tool name + one-line description without starting --stdio and speaking MCP.
• Refactor stdio tool descriptors into STDIO_TOOL_DESCRIPTORS as the single source of truth used by both server.registerTool and the new command (behavior unchanged).
• Wire tools into CLI_COMMAND_SPEC (shell completion), printHelp(), and the package README; assert CLI tool count/descriptions match the live registered stdio tools.

Closes #2233.

Scope

• The PR title follows type(scope): short summary Conventional Commit format, for example fix(api): restore profile access checks.
• This PR is focused and does not mix unrelated backend, UI, MCP, docs, dependency, and deploy changes.
• This follows CONTRIBUTING.md and does not reintroduce GitHub Pages, VitePress, site/, or CNAME.
• I linked a currently open issue this PR resolves (e.g. Closes #123) — a linked open issue is required for every contributor PR.

Validation

• git diff --check
• npm run actionlint
• npm run typecheck
• npm run test:coverage locally; codecov/patch requires ≥99% coverage of the lines AND branches you changed (aim for 100% on your diff so CI variance does not fail near the threshold). Global coverage is a non-blocking trend with a loose 90% backstop, not the gate.
• npm run test:workers
• npm run build:mcp
• npm run test:mcp-pack
• npm run ui:openapi:check
• npm run ui:lint
• npm run ui:typecheck
• npm run ui:build
• npm audit --audit-level=moderate
• New or changed behavior has unit/integration tests for new branches, fallback paths, and sanitizer boundaries

If any required check was skipped, explain why:

• MCP-package-only change under packages/gittensory-mcp/** + test/unit/mcp-cli-*.test.ts (Codecov ignores packages/** and test/**). Ran focused MCP CLI tests (mcp-cli-tools, mcp-cli-basics) and npm run build:mcp after rebasing onto current main. Remaining full-gate jobs left to CI path filters / validate.

Safety

• No secrets, wallet details, hotkeys, coldkeys, user PATs, private keys, raw trust scores, private rankings, or private maintainer evidence are exposed.
• Public GitHub text stays sanitized, low-noise, and does not imply compensation guarantees or optimization tactics.
• Auth, cookie, CORS, GitHub App, Cloudflare, or session changes include negative-path tests.
• API/OpenAPI/MCP behavior is updated and tested where needed.
• UI changes use live API data or real empty/error/loading states, not production mock/demo fallbacks.
• Visible UI changes include a UI Evidence section below with JPG/JPEG or PNG screenshots arranged as organized, captioned, clickable thumbnails. SVG screenshots are not used as review evidence. Review-only screenshots or recordings are not committed to the repository.
• Public docs/changelogs are updated where needed; changelogs are only edited for release-prep PRs.

UI Evidence

N/A — CLI/MCP packaging change only; no visible UI.

Notes

• Fresh PR after feat(mcp-cli): add tools command listing stdio tool descriptors #4222 was closed for draft conversion during review (review-evasion). This PR stays ready-for-review.

Review summary
This PR refactors the 31 hardcoded stdio tool description strings into a single STDIO_TOOL_DESCRIPTORS array consumed by both server.registerTool and a new `gittensory-mcp tools [--json]` CLI command, and wires the new command into shell completion, --help, and the README. The refactor is mechanical and low-risk: stdioToolDescription() throws immediately at module load if a registerTool call references a name missing from the array, and the added test asserts the CLI's tool list has the same count, names, and description text as the live MCP-registered tools (via listTools()), which also catches an array entry that isn't registered anywhere. It closes the linked issue #2233 directly, is narrowly scoped to the MCP CLI package, and CI is green.

Nits — 5 non-blocking

• gittensory-mcp.js:352-491 — STDIO_TOOL_DESCRIPTORS duplicates 31 tool names as a literal array that must stay hand-in-sync with each registerTool call; nothing enforces this at the definition site itself (only the runtime throw catches a missing entry, and the test catches an unregistered extra) — consider generating the CLI listing from the registerTool calls' returned metadata instead of a parallel list, though I recognize that's a bigger structural change than this PR's scope.
• toolsCommand() (gittensory-mcp.js:2164) lists tools in declaration order rather than sorted alphabetically — worth sorting for a more scannable `tools` output, similar to how `completion` lists commands.
• The file is now ~2325 lines (flagged by size heuristics); this PR isn't the place to split it, but it's worth a follow-up to move STDIO_TOOL_DESCRIPTORS + toolsCommand into a separate module now that they're decoupled from individual registerTool call sites.
• Consider deriving `tools --json` output directly from the McpServer's registered tool metadata (if the SDK exposes it) rather than maintaining STDIO_TOOL_DESCRIPTORS as a hand-kept parallel list, to close the last gap where the two could drift without a test catching it until CI runs.
• Sort STDIO_TOOL_DESCRIPTORS or the toolsCommand() output alphabetically by name for readability.

Addressed
The diff refactors all stdio tool descriptions into a single STDIO_TOOL_DESCRIPTORS array used by both server.registerTool and a new toolsCommand, adds the `tools` command with --json wired into CLI_COMMAND_SPEC and printHelp, and adds a CLI test that compares the tools output count/descriptions against the live registered stdio tools.

Signal definitions

• Related work = same linked issue, overlapping active PRs, or title/path similarity.
• Change scope = cached public metadata such as size labels, draft state, and review-burden hints.
• Validation posture = whether the PR provides enough public validation/test evidence for maintainer review.
• Contributor workload = public contributor activity and cleanup pressure, not a repo-wide quality failure.
• Contributor context = public GitHub/Gittensor identity context; non-Gittensor status is not a blocker.
